“…Lower VFA concentration also suggested that microbial fermentation of protein and starch was reduced due to SHE supplementation. In agreement, Hassanat and Benchaar (2013) reported a decrease in total VFA concentration and an increase in acetate molar proportion with the inclusion of tannins in an in vitro study. Reduction in total VFA concentration could be related to the formation of tanninÁcarbohydrate complexes that are less degradable (Martinez et al 2006).…”

Effect of sainfoin hay and pomegranate peel extracts on in vitro fermentation and protein degradation using the RUSITEC technique. Can. J. Anim. Sci. 95: 417Á423. The objectives of this study were to determine the effect of supplementation of sainfoin hay extract (SHE) and pomegranate peel extract (PPE) on in vitro rumen fermentation characteristics, protein metabolism and nutrient digestibility using rumen simulation technique (RUSITEC). The experiment was a completely randomized design with three treatments and four replications. Dietary treatments were: (1) control (10% barley silage and 90% concentrate), and control supplemented (2) with SHE (4.1 g catechin equivalent kg(1 dry matter; DM) or (3) with PPE (2.8 g tannic acid equivalents kg(1 DM). The experiment consisted of 10 d of adaptation and 7 d of data collection. Concentration of total volatile fatty acid (VFA) was lower (PB0.02), but molar proportion of acetate was higher (PB0.01) with SHE or PPE than control. Branched-chain VFA decreased (PB0.01) with PPE supplementation compared with control. Concentrations of large and small peptides were not affected but ammonia nitrogen (NH 3 -N) concentration decreased (P B0.01) with PPE supplementation. Digestibility of DM, starch and crude protein decreased (PB0.02) with SHE and PPE supplementation compared with control. Bacterial nitrogen production (mg d(1 ) and bacterial efficiency (g bacterial nitrogen kg(1 digested organic matter) were not affected by SHE or PPE supplementation. Overall, there were no differences in VFA concentrations, nitrogen fractions and nutrient digestibility between SHE and PPE except for the concentrations of branched-chain VFA and NH 3 -N, which were higher (PB0.01) with SHE versus PPE supplementation. In conclusion, supplementation of high-grain diet with SHE or PPE can decrease rumen by-pass protein; however, suppression of feed fermentation may decrease the feeding value of high-grain diet.

“…However, another study by Hassanat & Benchaar (2013), using various sources and concentrations of tannins on rumen microbial fermentation in vitro, showed that gas and total VFA production decreased as tannin concentration increased. This discrepancy could be owing to the usage of various types of tannins, because in the results obtained by Hassanat and Benchaar (2013), tannins from Valonea were the only tannin source that reduced methane production without affecting VFA concentration.…”

Mangosteen peel (MP), an agricultural by-product of tropical countries, has been reported to contain condensed tannins and saponins, which can affect rumen microbes to reduce enteric methane emission. In the present study, the effects of mangosteen peel on in vitro ruminal fermentation, gas production, methane production, fatty acid biohydrogenation, and microbial population were investigated. Results showed that MP at medium and high levels (25 % and 50 % replacing alfalfa) were able to reduce (P <0.05) in vitro methane production without affecting volatile fatty acid (VFA) production and the pH of the substrate. The lowering effect of MP on methane production was because of suppression of the rumen microbial populations, especially total protozoa and total methanogens. MP at the higher level (50%) reduced (P <0.05) the amounts of biohydrogenation for linoleic acid (C18:2n-6), α-linolenic acid (C18:3n-3) and the total C18 unsaturated fatty acids (UFA) owing to the reduction of the Butyrivibrio fibrisolvens population, that is, the most important rumen microorganism involved in the biohydrogenation process. In conclusion, mangosteen peel has potential to be used in ruminant livestock feeds, with the advantage of reducing ruminal methane production and biohydrogenation, without adverse effects on ruminal pH and VFA production. ______________________________________________________________________________________

“…Sin embargo, Tan et al (26) encontraron una reducción de la concentración de ácido propiónico con la inclusión de TC de L. leucocephala, mientras que otros estudios in vitro demuestran la capacidad de los TC de aumentar la concentración de ácido propiónico (28) . Es posible que la dosis de inclusión de los TC usando como fuente las arbóreas tropicales no sean suficientes para cambiar el patrón de fermentación y la población bacteriana ruminal (9,15,25) .…”

Emisión de metano en ovinos alimentados con RESUMENEl objetivo fue evaluar el efecto de los taninos condensados (TC) contenidos en el follaje de arbóreas tropicales, sobre el consumo de materia seca y orgánica (CMS, CMO), la digestibilidad de la materia seca (DMS) y emisiones de metano (CH4) en ovinos alimentados con una ración basal de pasto Pennisetum purpureum. Cuatro ovinos de pelo con un peso vivo promedio de 21.6±2.0 kg se sometieron a cuatro tratamientos en un diseño cuadro latino 4 x 4. Los tratamientos fueron P. purpureum (PP), P. purpureum + Havardia albicans (PPHA), P. purpureum + Bursera sim aruba (PPBS), y P . purpureum + Acacia pennatula (PPAP); el follaje de las arbóreas se incluyó en 300 g/kg de MS de la ración. El consumo, la digestibilidad y la producción total de metano entérico se midieron por periodos de 23 h. La producción de metano se midió en cajas de respiración de circuito abierto. El consumo y digestibilidad de la MS y materia orgánica (MO) entre los tratamientos PP, PPHA, PPBS y PPAP no se afectaron por la inclusión de los follajes de arbóreas en la ración (P>0.05). Cuando la producción de CH4 se expresó en L/kg del CMS, CMO o consumo de fibra detergente neutro los resultados fueron similares entre tratamientos (PP, PPHA, PPBS y PPAP) (P >0.05). Se concluye que los TC contenidos en el follaje de Havardia albicans, Acacia pennatula y Bursera sim aruba no afectaron las emisiones de CH4 al nivel de incorporación de 30 % de la MS; tampoco se observaron efectos en el CMS, CMO, DMS y concentración molar de ácidos grasos volátiles. PALABRAS CLAVE: Arboles tropicales, Metano, Ovinos de pelo, Taninos condensados, Ácidos grasos volátiles. ABSTRACTThe aim of the work was to evaluate the effect of condensed tannins (CT) containing in the foliage's on dry matter intake and organic matter (DMI and OMI), dry matter digestibility (DMD) and methane (CH4) emissions in sheep fed a basal ration of Pennisetum purpureum grass. Four hair sheep with an average live weight of 21.6±2.0 kg were allotted to four treatments in a 4 x 4 latin square design. The treatments were P. purpureum (PP), P. purpureum + Havardia albicans (PPHA), P. purpureum + Bursera sim aruba (PPBS), and purpureum + Acacia pennatula (PPAP), the foliage of tree was included 300 g/kg DM of the ration. Intake, digestibility of DM and total methane emissions (L/d) were recorded for periods of 23 h when sheep were housed in open-circuit respiration head boxes. Intake and digestibility of the dry matter (DM) and organic matter (OM) between treatments PP, PPHA, PPBS and PPAP, were not affected by inclusion the foliage's of trees in the ration (P>0.05). When the production of methane was expressed in L/kg of DMI, OMI or neutral detergent fiber intake, the results were similar between treatments (PP, PPHA, PPBS, PPAP) (P >0.05). It is concluded that CT contained in the foliage of Havardia albicans, Acacia pennatula y Bursera sim aruba not affected the CH4 emissions an levels of incorporation as 30 % of ration DM, since there are no effects on DMI, ...
